My boss has both a regular ADSL line and a fixed service
"T1ish" SDSL line. At various times BS has punched a real
T1 on _HALF_ of his two wires, cut his neighborhood wires
completely, punched another DSL customer on _HALF_ his wires
and disconnected his home telco for 8 hours when he called
about poor connect speeds on his ADSL.

He's REAL happy with BS. Meanwhile, my BS ADSL has been
trouble free for months. I did have to teach the guy how
to install the software they "require" to be installed.
Of course it bombed because I had a NEWER version of Netscape
already loaded. Very sad.
